qsu

The qsu ("kazoo") crate is a:

• service runtime that acts as a layer betwen the server application code and an operating system service subsystem (launchd, systemd, Windows Services)
• set of utility functions for working with services.

lib.rs:

qsu is a set of tools for integrating a server application against a service subsystem (such as Windows Services, systemd, or launchd).

It offers a thin runtime wrapper layer with the purpose of abstracting away differences between service subsystems (and also provides the same interface when running the server application as a foreground process). More information about the wrapper runtime can be found in the [rt] module documentation.

In addition qsu offers helper functions to register/deregister an executable with the system's service subsystem. These are documented [installer] module.

And finally it offers an argument parser to offer basic service registration/deregistration and running using a consistent command line interface. These are documented in the [argp] module.

Features

In addition there's a special wait-for-debugger feature that is only used on Windows. It will make the service runtime halt and wait for a debugger to attach just before starting the Windows Service runtime. Once a debugger has attached, it will voluntarily trigger a breakpoint.
